Injection Moulding Operator Stationary Plant & Machine Operators
SaveWhat Does an Injection Moulding Operator Do?
Injection moulding operators operate and monitor injection moulding machines, in order to cast products from thermoplastic materials. They regulate the temperature, pressure, and volume of plastic, according to pre-defined specifications. Injection moulding operators also remove finished products and cut-away excess material, using a knife or other hand tools.
